I used to live in Belgium and used high calcium hydrated lime to make my venetian plaster (with marble dust).

I moved in US and the only hydrated lime I can find is the Hydrated lime type "N" with some Magnesium hydroxide in it.
Do I have to consider the Magnesium hydroxide as a charge or will it be an issue ?

I would love to hear any opinion or experience on it. Thank you

magnesium is poorer grade burnt at different temp u would have to look at specs sheets to find your answer I think its what farmers use as well for PH reasons to soil I might be wrong

Magnesium hydroxide is , or should I say it's not, water soluble. If I continue, a specific lime producer in Devon might get pissed off and not only, as they sell similar formula as their own brand polishing plaster, which actually over trowels very easy .
